Diamond Hole Saw Set GEKO G65103, 5 pcs, diameters 6, 8, 10, 12 mm

GEKO G65103 diamond hole saw set includes five diamond-coated hole saws designed to cut precise round openings with diameters of 6, 8, 10 and 12 mm. The set is intended for use with compatible drills or rotary tools to produce clean holes in hard, brittle materials such as ceramic, porcelain, glass and tile. The diamond coating provides consistent cutting performance and extended abrasive life compared with uncoated cutters, making the set suitable for plumbing, electrical and tiling tasks that require accurate small-diameter holes.

Advantages

The diamond-coated cutting edges deliver efficient material removal and reduced chipping on brittle surfaces. Multiple diameters in one set cover common small-hole requirements without needing to change tools frequently. The holesaws are compact and lightweight for easy handling, and they can be mounted on standard drill arbors or compatible rotary tool adapters. The construction provides stable cutting action and predictable hole quality in tile, ceramic and glass.

Suitable for

• Drilling access holes for plumbing fixtures through ceramic and porcelain tiles
• Making cable and conduit entries through tiled walls for electrical installations
• Cutting small-diameter openings in glass and decorative tiles for mounting fasteners
• DIY tiling repairs and precision trades work requiring neat round holes

Key specifications

• Set composition: five diamond-coated hole saws
• Diameters: 6 mm, 8 mm, 10 mm, 12 mm (set includes sizes to cover small-hole needs)
• Cutting material: diamond abrasive layer suitable for ceramic, porcelain, glass and tile
• Intended tool interface: for mounting on compatible drill or rotary tool arbors
• Typical applications: wet or dry drilling on brittle hard surfaces (observe tool and material limits)

How to use

Select the hole saw diameter appropriate for the required opening and mount it on a compatible drill arbor or rotary tool adapter. Secure the workpiece and mark the hole position. For ceramic, porcelain and glass, start drilling at low speed and use light, steady pressure to avoid cracking. When appropriate for the material and the tool, apply water cooling or periodic pecking to reduce heat and clear debris. Complete the hole by withdrawing the cutter carefully once the cut is finished, then clean any remaining grit from the opening.

Usage recommendations

Use protective eyewear and gloves when drilling hard brittle materials. For best hole quality, begin with a pilot mark or guide, maintain low to moderate drill speed, and consider continuous or intermittent water cooling when cutting glass or glazed tiles. Avoid excessive force and allow the diamond abrasive to do the cutting to prolong tool life.
